Gunnuhver

Gunnuhver is a geothermal spring on the Reykjanes Peninsula featuring active mud pools that continuously release steam and reach temperatures hot enough to transform surrounding rocks into clay deposits. Two viewing platforms provide access to the area, with the higher vantage point on Kisilhol offering expansive views across the steam fields.

The spring received its name four centuries ago from a woman named Gunna, whose spirit was believed to haunt the area following a dispute over rent payment. This legend has shaped how the place was named and understood ever since.

The spring embodies Icelandic folklore through the tale of Priest Eirikur, who supposedly used a ball of yarn to guide Gunna's spirit into the boiling waters. This legend remains part of how locals and visitors understand the place today.

The area is reachable via accessible pathways leading to both viewing platforms, which offer different angles of the mud activity. Visiting during drier months makes the walk more comfortable, as the ground remains firmer and visibility of the steam plumes is less hampered.

The main mud pool stands out as the largest active mud pool in Iceland, with constant bubbling and steam emissions that define its character. This ongoing activity makes it one of the most striking geothermal displays in the region.
